Conductors and drain wire must be 20 AWG minimum
stranded, tinned copper. Individual conductors must be insulat-
ed with PVC, PVC/nylon, vinyl, Teflon, or polyethylene. An
aluminum/polyester 100% foil shield and an outer jacket of
PVC, PVC/nylon, chrome vinyl, or Teflon with a minimum
operating temperature range of –4 F to 140 F is required.
Table 5 lists cables that meet the requirements.
Table 5 — CCN Connection Approved Shield Cable
Table 6 — Color Code Recommendations
If a cable with a different color scheme is selected, a similar
color code should be adopted for the entire network. At each
system element, the shields of the communication bus cables
must be tied together. If the communication bus is entirely
within one building, the resulting continuous shield must be
connected to a ground at one point only. If the communication
bus cable exits from one building and enters another, the
shields must be connected to grounds at the lightning suppres-
sor in each building where the cable enters or exits the building
(one point per building only).
To connect the unit to the network:
1. Turn off power to the control box.
2. Cut the CCN wire and strip the ends of the red (+), white
(ground), and black (–) conductors. (If a different net-
work color scheme is used, substitute appropriate colors.)
3. Remove the 3-pin male plug from the base control board
in the main control box, and connect the wires as follows:
a. Insert and secure the red (+) wire to terminal 1 of
the 3-pin plug.
b. Insert and secure the white (ground) wire to termi-
nal 2 of the 3-pin plug.
c. Insert and secure the black (–) wire to terminal 3
of the 3-pin plug.
4. Insert the plug into the existing 3-pin mating connector on
the base module in the main control box.

IMPORTANT: When connecting to CCN communication
bus to system elements, use color coding system for the
entire network to simplify installation and checkout. See
